Introduction UUID Regex Java

In Java, UUID validation is a common requirement, especially when dealing with system identifiers and data exchange. The java.util.regex package in Java provides the functionality to validate UUIDs using regular expressions.

What is UUID Regex?

Java regex for UUIDs follows the standard 8-4-4-4-12 hexadecimal format.

The UUID Regex Pattern

Pattern: ^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$

How to Validate UUIDs in Java?

To perform UUID validation in Java:


import java.util.regex.*;

public class UUIDValidator {
    public static boolean isValidUUID(String uuid) {
        String regex = "^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(uuid);
        return matcher.matches();
    }

    public static void main(String[] args) {
        String uuid = "123e4567-e89b-12d3-a456-426655440000";
        System.out.println("Is UUID valid? " + isValidUUID(uuid));
    }
}

Uses of UUID Regex Java Validation

  1. System Identification: Validating UUIDs used as identifiers in software systems and applications.

  2. Data Consistency: Ensuring UUIDs maintain a consistent format across databases and APIs.
